Ground Combat Troops, UNITED STATES ARMY IN WORLD WAR II ;Washington,

2 See Ch. III, above, for WD estimates of initial Victory Program as a
guide for supply planning. The War Department Troop Basis was issued somewhat informally at first
and in 1944-45 very formally by G-3, WDGS, to provide a basis for the
activation and organization of units, including combat divisions.

6 For the growth of the Army by branches in 1942, in terms of
percentages and strength figures, see Greenfield, Palmer, and Wiley,
Organization of Ground Combat Troops, p. 210 and table, p. 203. See
also Strength of the Army report cited n. 1 (1) .

13 In fact, the peak strength of the Army (almost 8,300,000) did
not much exceed, and the number of divisions organized (ninety) did not
reach, the authorizations for 1943.

14 See Strength of the Army reports cited n. 1 (1) and Appendix
D, below.

15Ibid. The high point in 1942 was reached in September with an
overseas ratio of 20.7 percent.

16 Not all of these divisions and combat groups were complete. For
the shipment of divisions overseas by month, see below, Appendix F,
Shipment of Divisions, 1942. Unless otherwise indicated, the remainder of this section is based on the sources of, and tables in, Appendix E, below.
Since the various statistical summaries of Army overseas strength in
early December 1942 do not agree exactly, all figures cited are to be
taken, with the cautions noted in Appendix E, as the best estimates
available.

17 The figures cited in this section in connection with original
BOLERO planning are based mostly on those approved by the JCS in JCS 23
(14 March 1942), and on the Marshall Memorandum (BOLERO plan) itself.
JCS 48 (2 May 1942), intended as a revision of JCS 23, was not actually
approved. (For discussion on JCS 23, the Marshall Memorandum, and JCS
48, see Chs. VII, IX, above.)

22 Army forces in Latin America (including South America and the
Caribbean Defense Command) came to about 120,000 troops including 7 air
combat groups; troops in North America (including Newfoundland,
Greenland, Bermuda, Bahamas, and eastern and western Canada) to 30,000.

23 These figures are based on OPD Weekly Status Map, 4 Jun 42, ,AG 061 (4 Sep
45),They include
about 46,000 troops en route to destinations outside the continental
United States. For purposes of this computation, Iceland is classified as outside the
Western Hemisphere. For a simplified breakdown as of 31 May, by months, for, major theaters,
see Strength of the Army, 1 flay 46, pp. 56--57, prepared by Strength
Accounting Br, AGO, under direction of Strength Accounting and
Statistics Off, OCS.

24 As of the beginning of June 1942 divisions overseas, including
those en route, were: 34th Infantry and 1st Armored (en route).,
Northern Ireland: 5th, Iceland; 24th, 25th, and 2 7th, Hawaii Americal,
New Caledonia: 37th (en route) , Fijis; and 41st and 32d,
Australia. (See OPD Overseas Tr Basis, 1 Jun 42, filed in Off of Army
Comptroller.) Figures for air units in the Pacific as of the beginning of June 1912
are extremely confusing because of emergency transfers. Principal air
combat units were then located in Hawaii, Australia, and on the lines
of communication. For the overall distribution of air groups, see: (1)
OPD Weekly Status Map, 4 Jun 42, AG 061 (4 Sep 45)H and (2) OPD
Overseas Troop Basis, 1 Jun 42.)

26 During most of December the Americal Division, the 147th Infantry, the
reinforced 2d and 8th Marines of the 2d Marine Division, and ?Marine
defense battalions were the ground forces available to the Army command
tinder General Patch. (See Miller, Guadalcanal, p. 214.)

27 The divisions in the Central Pacific Area were the 24th, 27th, and
40th Infantry present, and 25th Infantry in process of transfer. The
three divisions in the South Pacific were the Americal, 37th, and 43d Infantry Divisions. In the Southwest Pacific were the 32d and 41st
Infantry Divisions.

28 The 25th Division began Moving to Guadalcanal from Hawaii on 25
November and arrived on 17 December 1942.

29 By 31 December 1942 current and projected strengths, air and ground,
for the South and Southwest Pacific, as shown on the ()PD Weekly Status
Map of that date (AG 061, 4 Sep 45) (reproduced in Chart 3, below),
were:

30 Figures based on (1) AAF Statistical Digest (1945), Table 1, p.
4: and (2) OPD Weekly Status Map, 31 Dec 42, AG 061 (4 Sep 45). In this
computation, total forces deployed in the war against Japan-including
Alaska and CBI amounted to approximately 461,000. Farces deployed against
the European Axis Powers--including Africa-Middle East and Persian Gulf
Service Command-numbered about 411,000.

31 The figures in this section are based on AAF Statistical Digest
(1945) tables, pp. 151-78. According to these tables, total aircraft an
hand in each theater at the end of December 1942 was: ETO, 944;
Mediterranean, 1,121 ; POA, 386: Far East Air Forces, 957: CBI, 271;
Alaska, 296; and Latin America, 539. The figures on airplanes have been checked against figures in (1) OPD
Weekly Status Map, 31 Dec 42, AG 061 (4 Sep 45), and (2) Tab Aircraft,
